The present invention concerns a process for preparing a microfibrous multilayer composite material comprising: 1) realizing a non-woven microfibrous semi-finished product made up of microfibres of one or more polymers dispersed in a polyurethane matrix (semi-finished product IE); 2) cutting the semi-finished product lengthwise into two layers; 3) buffing at least one layer on one side (side N) so as to extract the microfibres and form the nap, thereby obtaining a semi-finished raw product; 4) cutting at least one semi-finished raw product lengthwise parallel to the surfaces, producing an non-woven intermediate product, containing the buffed side (side N) and a waste layer (containing the side that has not been buffed&#x2014;side S); 5) coupling the non-woven intermediate product (on the side opposite side N) to a fabric made of polyethylene terephthalate fibres by means of the application of a thermoplastic polyurethane adhesive that can be cross-linked between the non-woven intermediate product and the fabric; 6) submitting the multilayer composite material to a jet dyeing process. The invention also concerns a multilayer composite material that can be obtained by the process of the invention and the use thereof for covering the internal side of roofs or headliners of vehicles and for covering furnishing elements.

Multifibrous multilayer composite material for applications in the automotive sector

The present invention refers to a process for the preparation of a non-woven microfibrous suede-like synthetic fabric that does not require the use of organic solvents and that makes it possible to obtain a finished product offering a good hand, excellent resistance to yellowing and high durability. It comprises needle-punching a felt of sea/island fibers, (a) impregnation with hot aqueous solution of PVOH having a degree of saponification of at least 94% or (b) impregnation with hot water followed by impregnation with cold PUR, removing the sea component, impregnating with PUR, coagulating the PUR, removing the PVOH, grinding the surface, dyeing and splitting in two sheets.

Process for the preparation of a non-woven microfibrous suede-like synthetic fabric

An artificial leather having a suede appearance and colors within the grey-black range and high color fastness comprising a microfibrous component and an elastomeric matrix; the microfibrous component consisting of polyester microfibers having a count of 0.01 to 0.50 dtex; the elastomeric matrix consisting of polyurethane consisting of soft and hard segments; the ratio between the elastomeric matrix and the microfibrous component ranging from 20/80 and 50/50 by mass; the microfibrous component containing carbon black pigment in a percentage of 0.05 to 2.00% by mass; the elastomeric matrix containing carbon black pigment in a percentage of 0 to 10% by weight; the carbon black always having an average dimension smaller than 0.4 microns. The average length of the tassel is between 200 and 500 microns. The soft segments consist of at least one polycarbonate diol selected from polyalkylene carbonate diols and at least one polyester diol. The hard segments consist of urethane groups deriving from the reaction between free isocyanate groups and water. The total content of carbon black is between 0.025 and 6% by weight.

Microfibrous fabric having a suede appearance, within the colour range of grey and black, with a high light fastness, and preparation method thereof

The invention refers to a process for the preparation of a microfibrous non-woven fabric based on polyester or polyamide microfibers immersed in a polyurethane matrix, and having a thickness equal to or less than 0.65 mm, a flat or slightly mottled appearance and a nap length of less than 350 &#x3bc;m. The non-woven fabric is used for the preparation of coverings for consumer goods, particularly for the preparation of covers and cases for electronic products.

Microfibrous product and the use thereof for the preparation of covers and cases

A composite material is described, comprising: (a) microfibers selected from synthetic microfibers; (b) elastomer/lamellar clay nanocomposite matrix; said lamellar clay being selected from organophilic lamellar clays and functionalized organophilic lamellar clays. Dyed chamois woven-non-woven fabrics are also described, obtained starting from said composite material.

Process for the production of a microfibrous chamois woven-non-woven fabric containing an elastomeric nanocomposite matrix

A high durability composite textile material, like a synthetic suede, is prepared according to a procedure that comprises the impregnation of micro-fibers non-woven fabric substrate with a polyurethane-polyurea solution. This polymer solution, is made by a pre-polymerization phase between diisocyanate and polyols, a dilution phase of the pre-polymer thus obtained and an extension step of the pre-polymer, the extension of the pre-polymer free isocyanate groups is carried out by means water addition.
